N tax code
Marriage Allowance transferor — you have given 10% of your Personal Allowance to your partner.
What this code means in practice
This code does not include a standard Personal Allowance — tax is calculated at a flat rate or with no free pay.
Your Personal Allowance is reduced by £1,260 to £11,310. This is beneficial if your partner pays income tax and would save more from the additional allowance than you lose.
